How can you build something for someone else if you don't have enough familiarity with them to imagine the world through their eyes?

Being a cheap bastard now means so much more freedom and choices later.

There is no well-trodden route to where I am, no formula to replicate.

You probably know me as a producer for 'This American Life', a top podcast in iTunes.

Startup investing is one of my things, but it is not my everything.

The only way I know to be awesome at startups is to be obsessively focused and pegged to the floor of the deep end, gasping for air.

It would be a lot cheaper for me not to have to raise tens of millions of dollars to elect progressive candidates who will raise my taxes.

The Sharks step right on each other's questions, and if I ever did that in Silicon Valley, I would be considered a pariah. I literally had to learn how to interrupt.

I had a blast. 'Shark Tank' embodies the American Dream. If you watch the show at home, you find yourself constantly hollering at the Sharks. Being able to sit next to them and call them out in real time was quite a privilege.

When you see a 'Shark fight' erupt, we aggressively want to understand what we are committing our money toward.

People get out ahead of themselves in debt with spending on all of their desires. But if you learn to live pretty simply and well, well under your means, you feel incredibly, incredibly rich, and that frees you up and gives you the option to start something new, to leave the job you're not excited about, where there might be a glass ceiling on you.

Just don't spend your money, and you're well on your way to becoming a millionaire.

For most people, Twitter is too hard to use.

For most people, Twitter feels lonely.

For most people, tweeting is scary.

Live Twitter can be built right into the main Twitter app, but it should certainly have its own tab so we can concentrate on the live experience free of distraction.

I don't drink coffee. Weird, I know. But I try to stay away from caffeine. That said, we are investors in Blue Bottle, which is delicious!

I find talented, driven, boundlessly ambitious people and help them solve problems that will hopefully improve the lives of millions. Sometimes this means investing in startup founders. Other times, it involves helping organize and fundraise for charity or politics.

The passive acceptance of exclusionary words and deeds is not okay.

When I think about Trump and the GOP, the blood really is on their hands.

One rule we have at my house is, be proud of what we invest in.

I think the institutions, principles, norms, and traditions that make the United States of America genuinely exceptional are at serious risk. It has been hard to think about anything else.

You can't necessarily tell when watching at home, but those pitches are usually an hour long each, and many are emotional, hilarious, and inspiring.

I want to make clear that my feedback comes from a place of loyalty and persistent gratitude. I love Twitter.

I believe there is no natural ceiling on the revenue Twitter can generate. I also believe that Twitter's reach can become more pervasive and its impact on the world more meaningful.

Make tweets effortless to enjoy, make it easier for all to participate, and make each of us on Twitter feel heard and valuable.

All broadcasts on Periscope need to be archived for playback permanently, unless the broadcaster chooses to delete the recording. So many treasured moments have been shared on Periscope only to vanish a day later.

Twitter can afford to build the wrong things. However, Twitter cannot afford to build the right things too slowly.

The Internet is not pervasive as it could be, or democratic.

I am retiring from startup investing. It's hard to leave all this behind right when things are going so well.

There simply isn't a way to do the show without investing in a bunch more companies.

Facebook is who you used to know; Twitter is who you want to know and things you want to know more about.
